Nonlinear element — In an electric circuit, a nonlinear element or nonlinear device is an electrical element which does not have a linear relationship between current and voltage. A diode is a simple example. The current I through a diode is a non linear function of … Wikipedia
Nonlinear photonic crystal — Nonlinear photonic crystals are usually used as quasi phase matching materials. They can be either one dimensional[1] or two dimensional.[2] Nonlinear Photonic Crystals Broadly speaking, nonlinear photonic crystals (PC) are periodic structures… … Wikipedia
Nonlinear optics — (NLO) is the branch of optics that describes the behaviour of light in nonlinear media, that is, media in which the dielectric polarization P responds nonlinearly to the electric field E of the light. This nonlinearity is typically only observed… … Wikipedia
Nonlinear distortion — is a term used (in fields such as electronics, audio and telecommunications) to describe the phenomenon of a non linear relationship between the input and output signals of for example an electronic device. Model For many devices, a linear model… … Wikipedia
Nonlinear filter — A nonlinear filter is a signal processing device whose output is not a linear function of its input. Terminology concerning the filtering problem may refer to the time domain (state space) showing of the signal or to the frequency domain… … Wikipedia
Nonlinear junction detector — The non linear junction detector, or an NLJD, is a device that illuminates a small region of space with high frequency, RF energy. Any non linear junction in the vicinity for example, and particularly, the p n junction will receive this energy,… … Wikipedia
Data storage device — Many different consumer electronic devices can store data … Wikipedia
Covert listening device — A covert listening device, more commonly known as a bug or a wire, is usually a combination of a miniature radio transmitter with a microphone. The use of bugs, called bugging, is a common technique in surveillance, espionage and in police… … Wikipedia
Position sensitive device — A Position Sensitive Device and/or Position Sensitive Detector (PSD) is an optical position sensor (OPS), that can measure a position of a light spot in one or two dimensions on a sensor surface. Contents 1 Principles 1.1 Isotropic Sensors 1.2… … Wikipedia
Gamma correction — Gamma correction, gamma nonlinearity, gamma encoding, or often simply gamma, is the name of a nonlinear operation used to code and decode luminance or tristimulus values in video or still image systems. [cite book | title = Digital Video and HDTV … Wikipedia
